Multi-Component Fibre and Production Method

Abstract

The disclosure relates to a method for producing a multicomponent fiber, wherein the fiber is formed from a plurality of filaments, where the filaments each have a core and a thermoplastic sheath, and where the sheath is generated during the production of the filaments by in situ polymerization of monomers or oligomers of the thermoplastic on the surface of the core, and also to multicomponent fibers produced accordingly and to organosheets produced therefrom.

1 . A method for producing a multicomponent fiber, wherein the fiber is formed from a plurality of filaments, where the filaments each have a core and a thermoplastic sheath, and where the sheath is generated during the production of the filaments by in situ polymerization of monomers or oligomers of the thermoplastic on the surface of the core. 
     
     
         2 . The method as claimed in  claim 1 , wherein the core of the filaments is produced by die drawing methods or spinning methods. 
     
     
         3 . The method as claimed in  claim 1 , wherein the core of the filaments is formed of glass, basalt, ceramic, metal, or plastic. 
     
     
         4 . A method for producing a consolidated, thermoplastic, semifinished, continuous fiber reinforced product or a component comprising it, the method comprising the steps of:
 producing a multicomponent fiber by the method as claimed in  claim 1 ,   producing a fabric from the multicomponent fiber,   
       making up the fabric, and 
       consolidating the made-up fabric into a consolidated, thermoplastic, semifinished, continuous fiber reinforced product or a component comprising it. 
     
     
         5 . A method for producing short fiber reinforced components, the method comprising the steps of:
 producing a multicomponent fiber by the method as claimed in  claim 1 ,   chopping up the multicomponent fiber into short fibers,   producing a fabric from the short fibers, and   
       making up the fabric into a short fiber reinforced component. 
     
     
         6 . The method as claimed in  claim 1 , wherein the core of the filaments is formed of glass.
